Transient changes of the intestinal absorption of sodium and chloride in the rainbow trout after abrupt transfer into sea-water

Plasticity of osmoregulatory function in the killifish intestine:drinking rates, salt and water transport, and gene expression after freshwater transfer

“…This suggestion is supported by the observation that the difference between net Cl -flux and net Na + flux appeared to increase after freshwater transfer. However, net Cl -fluxes are also higher than net Na + fluxes across the intestine of fresh water-acclimated flounder Platichthys flesus (Smith et al, 1975) and rainbow trout Oncorhynchus mykiss (Nonnotte et al, 1987), both of which can actively absorb Cl -at the gills, so this suggestion is uncertain. Furthermore, a recent review (Marshall and Grosell, 2005) has noted that an excess of Cl -over Na + absorption across the intestine is the normal pattern for a variety of marine species.…”
